Everything works fine without any issues but when I tried to install mongodb php module 'php.net/manual/en/mongodb.installation.pecl.php' (url) is missing on the rh-php56 list. rh-php56 only has support for rh-php56-php-pecl-mongo which is a deprecated library. Now I am kind of stuck with rh-php56 and am not sure how to install mongodb php module. So am wondering whether it's possible to install using 'softwarecollections.org/en/scls/remi/php56more/' (url) will it work with rh-php56 without any conflict? or do I have to uninstall the rh-php56 and install the php 5.6 using remi?

Sorry for the long explanation and question, this is a production server and am afraid to make changes without clear understanding of the changes I make.

Re: Cent OS 7.3 php56more

So, using centos-release-scl package (available on centos extras repository) you can get rh-php56-* packages (from RHSCL official collection) and sclo-php56-* additional packages maintained by the SIG (aka, by me).
